Total particulate matter (PM) emissions were estimated for recent fires (1979-1990) and the presettlement period (prior to 1935) in the Selway-Bitterroot Wilderness (SBW) in Idaho and Montana. Recent period emissions were calculated by 10-day periods for surface fire and crown…

The custom of annual burning of the woods from Colonial times onward is a subject of more interest, perhaps, to ecologists and social scientists than it is to foresters. The important point to us is that it had become a well-settled folkway by the time large-scale lumbering…

A nylon tent designed for firefighters was placed in a smoky environment in a wind tunnel. The close knit fabric screened out 95 percent of the particulate matter but none of the gases in the smoke. There was no oxygen depletion in the tent when a person was in or out even…
